822254 - Missing symbols for probably new win32 DLLs

Status: RESOLVED FIXED

Description

[Robert Kaiser]

At least for some Win7 and Vista DLLs, we now seem to be missing symbols, see the top items on https://crash-analysis.mozilla.com/rkaiser/2012-12-16/2012-12-16.firefox.17.explosiveness.html for example.

A few examples I pulled from a random set of crash reports:

Win7:
KERNELBASE.dll 	6.1.7600.17135 	486BB50357A24BC5A6EE88BB1FBBF7451 	wkernelbase.pdb
KERNELBASE.dll 	6.1.7600.17135 	33018FDD4369486EA70F4374FBCAD77E2 	kernelbase.pdb
KERNELBASE.dll 	6.1.7601.17965 	E1609DE3233B4EDF8211CF7E83211B401 	wkernelbase.pdb
KERNELBASE.dll 	6.1.7601.17965 	D0699EACAF4547299B4C8917FC1A490D2 	kernelbase.pdb

Vista:
kernel32.dll 	6.0.6002.18704 	57533A14965F4D99AF218C4507D953E02 	wkernel32.pdb
kernel32.dll 	6.0.6002.18704 	882A637ABACB4AD29751B511B0D3A5BF2 	kernel32.pdb


Ted, do we have those symbols on our servers? Is something wrong with the script that should pull those from Microsoft?

There's also Win8 ones missing:

KERNELBASE.dll 	6.2.9200.16451 	F073108B992B4AA9A1E9D51E49534A3B2 	wkernelbase.pdb
KERNELBASE.dll 	6.2.9200.16451 	DD4522B344B04180A82AA5F4E0378A1A2 	kernelbase.pdb

I can confirm that these symbols are definitely not present on the symbol server. I'll poke at the Windows symbol fetcher and see if I can determine why.

I don't have any insight here, I kicked off a manual run of the symbol fetch script, it looks like it's picked up a few of these (but I'm not sure why it wouldn't have in its nightly automated runs...).

I think we need to get some more visible logs out of this script so that we can diagnose things a little better.

Those were picked up, but I'm just right now filing yet another bug on another set of MS symbols missing.
